Renewable resources can provide a range of different polysaccharide blocks that be used to prepare new types stimuli-responsive polysaccharide-based block copolymers.

the role of vi-capsular polysaccharide (vi-cps) in human immunity against infection caused by salmonella typhi is well known. the downstream process of purification generally causes depolymerization of vi-cps to a nonimmunogenic low molecular weight form. in the present study, a standard strain of sal. typhi ty6s was grown under submerge cultural conditions in a pilot-plant scale of 90 liter fe...

this study examines the controlled release behavior of both water-soluble (acetaminophen, caffeine, theophylline and salicylic acid) and water insoluble (indomethacin) drugs derived from caesalpinia pulcherrima seed gum isolated from caesalpinia pulcherrima kernel powder. it further investigates the effect of incorporating diluents such as microcrystalline cellulose and lactose on caffeine rele...

Large quantities of phosphate present in wastewater is one of the main causes of eutrophication that negatively affects many natural water bodies, both fresh water and marine. It is desirable that water treatment facilities remove phosphorus from the wastewater before they are returned to the environment. Total removal or at least a significant reduction of phosphorus is obligatory, if not alwa...

Our previous study revealed that the antioxidant activity of polysaccharide (coded as FGFP) extracted from Grifola frondosa by enzymolysis treatment was significantly superior than that (coded as GFP) extracted by boiling-water. In this study, one purified polysaccharide fractions (coded as FGFP-11) was obtained from FGFP by purified using DEAE-52 column and Sephacryl S-500HR column. Results in...
